Development of an eco-friendly composite material for engineering applications
… is to assess the performance of flax fibre/waste glass cement composites. Flax fibres are used to reinforce two systems. The first system contains Ordinary Portland Cement (OPC) only as a binder while in the second system a part of OPC is replaced by finely ground waste glass powder. The fibre …

Effect of rigid crystals on the experimental sintering of rhyolitic ash under shallow conduit conditions
… minutes to 9 hours. A 50/50 mixture of rhyolitic glass powder (<45 μm) and quartz crystals, in three distinct size distributions, were used: 250 - 500 µm, 90 - 125 µm, and 45 - 76 μm. All samples evolved similarly, from loose, cohesion-less particles to sintered particles forming a friable, …

The kinetics of ion release by glass-ionomer cements
… one in-house conventional GIC made from G338 glass powder, one commercial glass-ionomer bone cement and four in-house novel aluminium free Fe2O3 based GICs. Cylindrical specimens of GICs were prepared in stainless steel moulds to form 6 mm height x 4 mm diameter cylinders which were then …

Characterisation and Evaluation of Thermally Treated Recycled Glass for Mass Finishing and Superfinishing Processes
… based wholly on thermally treated recycled glass, which acts as both a bond and abrasive for mass finishing and superfinishing processes. The recycling of glass is excellent in respect of sustainability and environmental efficiency. The aim of the study was to establish requirements for the …

Development of sustainable material for hybrid wall system to improve indoor thermal performance
… locally available waste materials such as waste glass and oil palm industry byproducts. The enhancement of thermal performance of wall materials was done by the introduction of cellular porous palm oil fibers to lower the heat transfer. Fiber reinforced mortar (FRM) and thermally enhanced …

Experimental studies on the adsorption of SO2 on volcanic ashes
… of SO2 on synthetic and on natural volcanic glasses was studied. The synthetic glasses were of rhyolitic, dacitic and andesitic composition and were synthesized in a high-temperature furnace at 1600°C. The natural volcanic glasses were Lipari obsidian and Puu Waawaa obsidian. Before the …

Coupling source term, mineral reactivity and flow in radionuclide transport
… of UK high-level nuclear waste borosilicate glass, and to predict its performance in the near field of a geological repository. A single-pass flow-through (SPFT) experimental system was used to measure the forward dissolution rates of MW25. Experiments were conducted in two parts. Experiment …

Étude de la durabilité des bétons de matériaux alcali-activés
Les matériaux alcali-activés (MAA) sont considérés comme une alternative pour réduire l’utilisation du ciment Portland. Ces matériaux, développés il y plus de quarante ans, présentent des propriétés mécaniques similaires ou supérieures à certains bétons de ciment Portland. De plus ces matériaux …
